WINDOW-FASTENING.

`Specification of Letters Patent.

Patented Apr. 13, 1915.

Appncation mea 'september as, 191s. serial No. 791,889.

T all 'whom t may concern:

Be it known that I, WILLIAM C. KENTZER, a citizen of the United States of America, re siding at New Rochelle, county of vWestchester, Stateof New York, have invented certain new and useful Improvements lin Window-Fastenings,of which the following is a specification.` i i This invention relates-to an improvement in window sash fastening devices and has for its object the providing;- of means whereby the sash may be permanentlylockedin any pre-determined position by means operatingf from the inside of the window and by locking means operating between the win- "dow sash and the strip forming; that side of the way in which the window moves toward the inside of the4 house, thus providing.' aA

locking means which cannot be tampered with from the outside of the window without removing the outside window guide and the window sash; in other words, thelocking means is protected from external manipulation by reason of the fact that it lies entirely on the inside of the window sash.

The means which I provide to operate the locking means is operated by pressure in the same direction to lock or release the locking device.

I am aware that window sash locking'devices'are known in the art whereinthe locking bolt iinds its keeper in the external side ofthe way within which the window frame moves. A'serious objection is found 'in such devices in that this outside strip of the wayV in which the window -moves may be' readily tampered with by introducing' an instru-.-

ment between the sash and the outside section of Vsaid way for the purpose of manipulating the locking means or said section may be readilybrOkem'thUs releasing' the lockingmeans from the outside.

In the preferred form of the inventionthe fastening means consists of abolt adapted to. be projected at right anales to-the plane ofV the glass. vThis may be conveniently arj rangedtoengage'a `member rigidly secured to the wlndow frame and covered and pro-i tected by the sash itself.

In the device shown, each bolt is actuated by a plurality of members which maybe in the form of. push buttons, the buttonsbeing projecting and retracting means.

connected to the bolt by lseparate means so that one servesto advance or project the bolt while 'the other serves to retractit. The buttons-are preferably so arranged that they are operated from the direction in which the bolt is projected, so that both the buttons and the fastening means or bolt and its keeper may be protected to the best advantage, being placed inside the sash and away from the outside of the window.

In the accompanying vdrawings I have illustrated a preferredform of my invention.

In these drawingsfFigure l is an elevation of a portion of a window provided with the fastening` means of the invention, the greater portion of the window illustrated being broken away for convenience in illustration. Fig. 2 is an elevation of the locking device taken from the inside ofthe window,

the cover of the lock being removed to show the bolt and the mechanism ofthe lock or Fig. 3 is an elevation of a fragment of the plate in which the bolt sockets are formed. Fig. 4 is a horizontal section throughV the lower sash,

the section being taken through the lock so as to show the bolt and projecting and re- Referring to the drawing by numerals, each of which is used to indicate the same 0r similar parts in the different figures, I have shown an upper sash l, a lower sash 2, a fastening device 3 on the lower sash and 4 on the upper sash, and akeeper strip 5 for the lower sash and 6 for the upper sash. The keeper strips .are preferably L-shaped in cross-section as shown in Fig. 4, the strip 5 for the lower sash being placed with one arm ofthe L between the lower sash and the retaining strip 7, and the other arm between the retaining strip and the window frame proper 8, the keeper strip 6 for the upperA sash, likewise L-shaped in cross-section, hav- .adapted to receive the bolt and arranged to vconform vto the various positions in which it is desired tolock the sash.
